IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 157,193, dated November24, 1874; application filed September 19, 1874.

To all whom it may concern:

Be it known that I, HENRY O. CHAPMAN, of Port Jervis, in the county ofOrange and State of New York, have invented a new and ImprovedOar-Coupling, of which the following is a specification:

The invention here presented represents a new and useful device forcoupling and uncoupling cars without the necessity of the brakeman goingbetween the same, the outer end of the coupling-link being raised orlowered by a looped rod, in which the link rests, and by which the saidlink may be elevated or depressed to suit the various heights ofdraw-heads on dili'erent cars and, furtherm ore, by having a recess madein the face of the draw-head, into which the looped rod which supportsthe link may recede when the cars bump together, it will prevent thesaid rod from being broken or jammed in the collision, the constructionand operation of which will be understood from the followingdescription, reference being had to the accompanying drawing formingpart of this specification.

- Figure 1 represents a sectional side elevation, showing two carscoupled. Fig. 2 is an end view, showing the coupling -pin disengaged.

Similar letters of reference indicate corresponding parts.

In the case here presented the letter A represents a rod extendingacross the end of a car, and securely attached thereto by staples,cleats, or other suitable means, forming bearings in which it mayrotate. The said rod is shaped as shown in Fig. 2, having a crank, B, ateach end, and a U-crank, J, in its center, from which the couplingpin Ois suspended by means of a hook, l), which is attached to or swings fromthe swivel-plate E. The letter F represents a rod suspended from theaforesaid swivel-plate. The said rod has a loop, slot, or ring, G, whichfits loosely over the coupling-link H, and serves to support the same atany desired inclination, thus enabling the brakeman to adjust the linkwithout the necessity of going between the cars; and to prevent breakageor injury to the said rod when the cars bump together, I have a recess,I, made in each draw-head, into which the rod may run and thus beprotected.

Vhen the above-described rod F is not required to be used it may be hungover a hook provided for it, as shown in Fig. 2.

Having thus described my invention, I claim as new and desire to secureby Letters Patcut-- The looped rod F, for supporting and holding thelink H at any desired inclination, the rod being suspended from aswivel-plate on the U-crank J, all combined substantially as described.

2. The swivel-plate E, in combination with the looped rod F and hooks D,to give ease and flexibility to their movements, substan tially asdescribed.

HENRY O. CHAPMAN.
